Setup Openmetadata

OpenMetadata is an open-source metadata management system that is built on top of Kubernetes and Apache Cassandra. To set it up on Linux, you can follow these general steps:

1. Install Kubernetes:

• First, you need to install a package manager such as apt or yum depending on your Linux distribution.
• Next, you need to add the Kubernetes package repository to your system, this can be done by running the following command:

curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -

• Then, you need to add the Kubernetes package repository to your system by running the following command:

echo "deb http://apt.kubernetes.io/ kubernetes-xenial main" > /etc/apt/sources.list.d/kubernetes.list

• Finally, you can install Kubernetes by running the following command:

apt-get update && apt-get install -y kubelet kubeadm kubectl

2. Install Apache Cassandra:

• First, you need to download the binary package of Cassandra from the Apache Cassandra website.
• Next, you need to install the package by running the following command:

dpkg -i <package-name>.deb

• Then, you need to start the Cassandra service by running the following command:

systemctl start cassandra

• Finally, you need to configure the Cassandra cluster by editing the cassandra.yaml configuration file.

3. Clone the OpenMetadata repository:

• First, you need to install Git on your Linux system.
• Next, you need to clone the OpenMetadata repository by running the following command:

git clone https://github.com/open-metadata/open-metadata

4. Deploy the OpenMetadata components using Helm:

• First, you need to install Helm on your Linux system.
• Next, you need to add the OpenMetadata Helm repository by running the following command:

helm repo add openmetadata https://open-metadata.github.io/charts

• Then, you need to install the OpenMetadata chart by running the following command:

helm install openmetadata/openmetadata

5. Configure the OpenMetadata components:

• You need to modify the values in the Helm chart to configure the OpenMetadata components. This may include setting up the connection to the Cassandra cluster, configuring the authentication and authorization settings, and so on.

6. Use the OpenMetadata APIs:

• Once the installation is complete, you can use the OpenMetadata APIs to manage and access metadata in your organization. The APIs can be accessed through the Kubernetes cluster IP.
